A leaky, decrepit boat bearing an illegal and highly dangerous cargo of phosphorus sets out from Africa on the long voyage to Caracas. Also on board is a motley collection of misfit passengers, all with shady pasts which they are keen to escape. When the captain/owner Lansen ignores a hurricane warning, most of his crew desert the boat, which is now in danger of being blown apart by the explosives in the hold. Lansen and the passengers insist on going on, but soon drift into the Sargasso Sea, filled with terrifying monsters and the remains of ancient galleons. Then they discover a land peopled by the descendants of fanatical Spanish conquistadors and ruled by a young boy known as ‘El Diablo’.
